The CJ (CTEQ-Jefferson Lab) Collaboration studies the quark and gluon structure of the nucleon by performing global QCD fits of parton distribution functions (PDFs). These parametrize a vast array of data including deep-inelastic lepton-nucleon scattering, proton-proton collisions (lepton pair creation, W-boson and jet production), and other reactions, with particular focus on the large-x region.
The JLab Theory Center is engaged in a range of outreach activities aiming to disseminate its specific knowledge and research to the broader academic community, attract and train future generations of scientists, and promote the awareness and understanding of science in society at large. Programs are aimed at university students at the graduate and undergraduate level, K-12 students in local school systems, and social media audiences.
